Product Introduction：
Tempered glass insulator products are used for insulating and suspending wires in high-voltage and ultra-high-voltage AC and DC transmission lines.
The product is composed of iron cap, tempered glass parts and steel feet, which are glued together with cement adhesive. This product all adopts the most advanced cylindrical head structure in the world, and its characteristic is that the head size is small. Light weight, high strength and large creepage distance. It can save metal material and reduce circuit cost.
